The PHS-3C intelligent pH meter is suitable for measuring the pH value and mV value of aqueous solutions. If equipped with an ion electrode, the ion concentration of the solution can be measured by measuring the ion electrode potential, and it can also be used as an endpoint indicator for potential analysis.

Functional features:

Microcomputer based Circuit Design
The instrument is equipped with high-performance microcomputer chips, and all electronic components are soldered using surface mount technology for precision and reliability. The highly integrated circuit design not only reduces the internal wiring of the instrument, but also improves measurement accuracy and enhances anti-interference ability.

Automatic calibration
The instrument adopts a two-point button for automatic calibration. During calibration, the screen has a standard buffer solution prompt function. Simply place the electrode sensor into the corresponding solution according to the screen prompt and press the calibration button. The instrument will automatically calibrate the pH value of the current standard buffer solution at the temperature value you set.

Automatically identify standard buffer solutions
During calibration, if the user does not use standard buffer or uses a standard buffer that does not match the instrument prompt, the instrument willAutomatic alarm.

Automatic electrode slope display
After calibration, the instrument will automatically display the percentage of electrode slope and make a judgment on the electrode condition. You can determine whether to replace the electrode based on the icon display.

automatic temperature compensation
The PHS-3B intelligent laboratory pH meter is equipped with a temperature sensor, which can measure the temperature of the sample solution. When used together with a pH composite electrode, the instrument can be dynamically temperature compensated.

Large screen LCD display
The customized LCD display screen is simple and bright, not only displaying the measurement values of the instrument clearly, but also having operation status icons.
